Taking her sons Sean Preston, 10, and Jayden James, nine, out for a boogie board at Planet Hollywood's pools, the 34-year-old is making the most of the Las Vegas heat wave, which has seen temperatures soar to the early/mid-40s (degrees Celsius).

But as you can see above, Brit's bringing the heat all on her own. In one clip, she shows off her figure under a fake waterfall, captioning the video: "Twirling for all the haters."

The next clip shows the Vegas performer's pretty solid attempt at boogie-boarding in the Flowrider wave pool. She's lucky a bikini malfunction didn't strike…yes, she's so lucky, she's a star (see what we did there, Britters fans?).

She also shared this shot, writing: "My head is melting it's so hot in Vegas!!" No Britney, it's just you, girl.
